The Ontario Natural Building Coalition's Annual 

Ontario Natural Homes Tour

Natural building construction uses locally obtained and renewable materials, to produce homes and buildings that are visually unique and healthy to live in, while striving to keep energy consumption 

and its’ associated emissions as low as possible. 

As a way of promoting natural building, the Ontario Natural Building Coalition coordinates an 

annual Natural Homes Tour, taking place this year on Sunday September 24th from 10am-4pm.  

Dozens of natural homes and buildings across Ontario will open their doors for participants to see 

examples of straw bale, rammed earth, cob, timber frame, off grid, passive solar, and many 

other natural building methods and alternative technologies. 

Click on the map below to view locations and descriptions of the homes on the tour. Check back often as new homes and buildings are added frequently!

This event is an important fundraiser for us - read about why

Cost is $10 for the day. Tickets available here. (OR purchase one at the first home you visit)

Download and print a list of the home locations.

Again this year we are partnering with Green Energy Doors Open, which has numerous locations open to the public on Sunday September 24th - offering many options of places to go and see!

Green Energy Doors Open is an energy literacy communications campaign and annual showcase of individual, community and commercial sustainable energy projects organized and spearheaded by the Ontario Sustainable Energy Association. The initiative aims to showcase advancements in the sector, demonstrating that Ontario is already on the path to building a 100% clean, sustainable energy system. 

The Green Energy Doors Open showcase weekend celebrates sustainable energy projects and success stories across Ontario. During Green Energy Doors Open, businesses, organizations, and community groups will open their doors and host free events to promote their sustainable energy initiatives.

A Natural Home Tours Thank You

Over the years, many homes and buildings have participated in our Natural Building Annual tour.

Many of the homes that have been featured were models of innovation and energy efficiency and featured living roofs, natural clay wall finishes, rainwater catchment systems, grey water systems, composting toilets, while others incorporated solar and wind electrical systems, high efficiency wood burning appliances, solar domestic hot water systems, as well as a variety of other interesting green technologies.

The Ontario Natural Building Coalition would like to thank all the volunteer homeowners who have over the years graciously opened their doors and welcomed tour-goers. The annual tour would not be possible without them!
